There is currently no clear strategy for dealing with large-scale contamination projects without causing obstacles to dealing with small-scale ones (brownfields). Following the Love Canal incident, CERCLA, the Comprehensive Environmental Response, Compensation, and Liability Act (or Superfund) was legislated, and the Environmental Protection Agency (EPA) was authorized to clean up contamination from past disposal practices that pose risks to human health or the environment. It is estimated that at least 200,000-500,000 sites (brownfields) in the United States contain polluted soil or groundwater that may require remediation to overcome the negative effects of past industrial operations. The book aims to evaluate the program's ability to cope with the uncertainties at large contaminated sites while still being able to achieve flexibility for the redevelopment of comparatively smaller parcels.
Deals with the geotechnical aspects of the design of underground openings for mining and civil engineering processes.
Results and conclusions of the "IEA-SSPS High Experiment" are presented together with the thermodynamic theory of the Advanced Sodium Receiver. During the experiment, flux distributions, surface temperature distributions, efficiencies and losses, were measured and calculated in a power range of 0.8-3.5 MW at different sodium inlet/outlet temperatures. The design heat flux of 1.4 MW/m2 was increased to 2.5 MW/m2 resulting in a slightly increased total receiver efficiency of over 90%.
Ten years ago the author, together with eight co-authors, edited a textbook Remote Sensing for Environmental Sciences within the series on Ecological Studies of Springer-Verlag. At that time there were not yet many books available on remote sensing. The decade that has elapsed was marked by a spectacular development in this field. This development took place in many directions: by widening the areas of application, by improvements of the methods and the sensors, by the introduction of new versatile platforms, but also by deepening the knowledge of the theoretical foundations. This evolution improved the ability to explain the interaction between electromagnetic radia tion and natural objects, which, in its turn, allowed for better modelization and for the creation of refined mathematical tools in the processing of remotely sensed data and in the determination of the physical status of remote objects. The community of research workers engaged in development and use of remote sensing methods changed accordingly from a modest group of scientists in the early 1970's to a considerable branch of specialized and interdisciplinary activity. The training of students had to be adapted to cope with the increasing number of people entering this new field and with the increasing quality of the material to be presented."

During 1978-1982 the International Institute for Applied Systems Analysis (IIASA) was responsible for a research project on Environmental Quality Control and Management. The project was begun under the direction of Professor O. F. Vasiliev (from the Institute of Hydrodynamics of the Siberian Branch of the USSR Academy of Sciences) and was subsequently led by myself. This review is very much a re'fiection of that IIASA project. The major themes of the IIASA project were: (i) research into the methodological aspects of modeling river and lake sys tems [some of the principal results of this research appear in M. B. Beck and G. van Straten (eds. ) (1983), Uncertainty and Forecasting of Water Quality (Springer, Berlin (West)), and in K. Fedra (1983), Environmental Modeling Under Uncertainty: Monte Carlo Simulation (IIASA Research Report RR-83-28)]; (ii) case studies in the application of mathematical models to lake eutrophi cation control [results of which are summarized in L. Somlyody, S. Hero dek, and J. Fischer (eds. ) (1983), Eutrophication of Shallow Lakes: Model ing and Management (The Lake Balaton Case Study) (IIASA Collaborative Proceedings CP-83-S3), and in K. Fedra (1983), A Modular Approach to Comprehensive System Simulation: A Case Study of Lakes and Watersheds (in W. K. Lauenroth, G. V. Skogerboe, and M. Flug (eds. ), Analysis of Ecological Systems: State-of-the-Art in Ecological Modelling, pp. 195-204. Elsevier, Amsterdam)]; iv (iii) a policy study of operational water qua,lity management [M. B. Beck (1981), Operational Water Quality Management: Beyond Planning and Design (IIASA Executive Report ER-7)].
The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication.

Traditional textbooks on rock mechanics often fail to engage students in the learning process as such books are packed with theory that students are unlikely to use in their future employment. In contrast, this book delivers the fundamentals of rock mechanics using a more practical and engaging project-based approach which simulates what practitioners do in their real-life practice. This book will be of great help to those who would like to learn practical aspects of rock mechanics and better understand how to apply theory to solve real engineering problems. This book covers geology, rock mechanics principles, and practical applications such as rock falls, slope stability analysis and engineering problems in tunnels. Throughout the whole book, the reader is engaged in project-based work so that the reader can experience what rock mechanics is like and clearly see why it is an important part of geotechnical engineering. The project utilizes real field and laboratory data while the relevant theory needed to execute the project is linked to each project task. In addition, each section of the book contains several exercises and quiz questions to scaffold learning. Some problems include open-ended questions to encourage the reader to exercise their judgement and develop practical skills. To foster the learning process, solutions to all questions are provided to allow for learning feedback.

This volume is the result of years of commitment with world-wide sanitation challenges from various research networks linking the editors and authors of this volume to many other sanitation scholars and professionals. Major contributions to this volume are derived from the work done in the PROVIDE project (working on sustainable urban infrastructures in cities of the Lake Victoria Basin, East Africa), the DESAR project (research and pilot projects in Decentralized Sanitation and Reuse, the Netherlands), and among others within NETSSAF (large scale implementation of sanitation in Africa), and EcoSan networks. The major milestone for this book to emerge was however the IWA Sanitation Challenge Conference of May 2008 in Wageningen, the Netherlands where all the authors of this book presented their papers. The conference was organized by a consortium of sanitation specialists at Wageningen University's Environmental Policy Group (the editors) and the s- department of Environmental Technology, LeAF (Lettinga Associates Foundation) and Wetsus (Center of Excellence for Sustainable Water Technology in the Netherlands). It was a unique event as it enabled a truly multi-disciplinary approach in discussing Sanitation Challenges in North and South with social and political scientists, natural scientists, environmental engineers and practitioners in one s- entific conference. This volume presents a selection of the social scientific insights and research results presented at the Sanitation Challenge Conference: the concepts, decisi- making support tools and the perspectives from farmers and consumers towards sanitation innovation.

Microbes are the predominant form of life on the planet due to their broad range of adaptation and versatile nutritional behavior. The ability of some microbes to inhabit hostile environment incompatible with most forms of life means that their habitat defines the extent of the biosphere and delineates the barrier between the biosphere and geosphere. The direct and indirect role of microbes that include bacteria, fungi, actinomycetes, viruses, mycoplasma, and protozoans are very much important in development of modern human society for food, drugs, textiles, agriculture, and environment. Furthermore, microorganisms and their enzyme system are responsible for the degradation of various organic matters. Microbes for Sustainable Development and Bioremediation emphasizes the role of microbes for sustainable development of ecosystem. Environmental microbiology role in biogeochemical cycle and bioremediation of environmental waste is major theme, which comprises the following aspects: Bacterial phytoextraction mechanism of heavy metals by native hyperaccumulator plants from complex waste-contaminated site for eco-restoration Role of microbial enzyme for eco-friendly recycling of industrial waste Field-scale remediation of crude oil-contaminated desert soil and treatment technology Microbial technology for metal recovery from e-waste printed circuit board Impact of genomic data on sustainability of ecosystem Methane monooxygenases: their regulations and applications Role of microbes in environmental sustainability and food preservation This book will be directly beneficial to researchers and classroom students, in areas of biotechnology, environmental microbiology, molecular biology, and environmental engineering with specialized collection of cutting-edge knowledge.
The enormous public interest of specialists as well as of engaged and concerned citizens in the energy problem can be understood in view of the fact that the future of national and world-wide economy depends on the availability of sufficient primary energy. The questions arising are: which forms of primary energy exist principally? by what means and at what cost can they be brought to useful application? and what is their possible role in the present and future energy scenario? Another reason which may not be so obvious, but which eventually may prove to be of great importance as far as public acceptance of energy technologies is con cerned, lies in the fact that the existing conscious or subconscious fears arising from confrontation with scientific and technological progress - to which even for the educated layman intellectual access is diffi cult - have been sublimated onto the energy problem and especially onto the problem of nuclear energy. Un like other developments, the emergence of nuclear ener gy has brought to our notice the ambivalence of ad vancing science and technology, which may either be used peacefully or misused militarily. Nuclear energy can help to overcome the increasing hunger for energy in the world, but it can also lead to the extinction of human life from the surface of this plant. More and more, mankind is confronted with chances and risks of new discoveries.

As society becomes stressed by economic and population pressures, in turn, nature's renewable resources become stressed by harvesting pressures. For our own survival and euphoria, it is paramount that such resources remain as their name implies and not be driven to extinction through short term programs of over exploitation. Consideration of the harvesting of renewable resources leads to a simple question that was the theme of the workshop and is the focus of these proceedings: SUPPoRe you are assigned the role of manager for a specific renewable resource eco system. How would you decide on harvesting policies so that the system can be exploited economically yet at the same time maintain the integrity of the system? This, of course, is a loaded question. First of all, it is not clear that there is ever anyone single decision maker who is able to set the rules for all of the harvesters in an exploited ecosystem. The political process is complicated and to some extent unpredictable. This aspect of the question is recognized to be important, but could not be addressed here. Assuming then that someone really is in charge, what would be involved in the * decision making process? As Clark points out, "there is no alternative but first to model the system. " We agree. However, if the original question was loaded, modeling is the adulterate."
This book states the harsh truth: that despite best intentions, our current environmental practices are doing more harm than good, and that the solution lies in creating supply chains of the future that design, produce, consume, and reuse materials in a manner that is balanced economically and environmentally. One billion beverage containers are used on a daily basis in the United States, with at least 600 million of them ending up in landfills. Even the 400 million that are recycled-at a great cost-are not accomplishing the task of helping the environment. This economic and environmental catastrophe cannot be solved by recycling programs. From his experience as a leader in the American consumer beverage industry and a researcher in Sweden, author Jack Buffington has developed a transformational solution that seeks to not just mitigate the environmental damage but jumpstart the economy while actually achieving zero waste. The Recycling Myth tells the story of how our current environmental practices are unintentionally doing more harm than good and how we need to create a radically different supply chain of the future that must, as best as possible, copy the natural system of growth, decay, and regrowth, and discontinue a disastrous pattern of material design and use. Backed by irrefutable evidence, the book destroys our comfortable notions of the recycling status quo; explains why recycling will never work in the United States, despite decades of attempts; and introduces a new system that will actually work-without asking consumers to consume less. Supplies an informed perspective from a leader in the consumer beverage industry at one of the world's largest producers of packaged beverages and a researcher in Sweden in the fields of environmental science and supply chain logistics Presents a bold counterargument to the idea that recycling and sustainability programs are inherently beneficial and introduces a new system that will benefit both our environment and economy-without asking consumers to consume less Explains why recycling and sustainability programs are ineffective because they focus solely on doing less harm rather than improving both the economy and the environment
Transportation Tunnels, 2nd Edition provides a comprehensive text on tunneling and tunnel engineering applicable in general to all types of tunnels, with more detailed information on highway and railway tunnels. While the First Edition of the book was confined to deal with railway and highway tunnels, the Second Edition is also extensively considering the latest trends in use of tunnels in different other fields. The book has been revised to provide coverage of water conveyance, navigation and material conveyance tunnels also and deals with these subjects in more detail. It covers all aspects of investigation, design, construction, monitoring and maintenance of tunnels. Special emphasis has been laid on the geotechnical investigations, interpretation of findings and relating the same to the design as well as the construction of tunnels. The book reflects the advancements in the knowledge of ground behaviour and rock mechanics and also in construction technology, including use of TBM in the last two decades. It covers in sufficient detail the basic requirements of tunnel profile, the geometric parameters, clearance requirements, aerodynamics, and cost economics in fixing alignments with different design parameters like curvature, gradient and operational requirements. It discusses in detail alternative forms of the cross section / profile and illustrates design methodology with examples. The different methodologies that have been used in the past using timber or steel supports by stage wise expansion of cross sections and modern methodologies used for boring full profile using new tunneling methods and Tunnel Boring Machines are also comprehensively discussed. Requirements of tunnels in respect of ventilation, lighting and drainage are adequately covered. Separate chapters have been included on 'Instrumentation' and 'Tunnel Inspection and Maintenance'. The expanded text on the use and advantages of methodologies and equipment for dealing with various aspects of construction of tunnels is based on observations through site visits, discussions with, and experiences of people as recorded on large number of tunneling works which have been taken up recently for railways, highways and urban transport subway projects. The book can serve as a textbook for undergraduate and graduate students and as a reference book for practicing engineers.
The book guides specialists and non-specialists from around the world on how or whether anaerobic processes can be part of solutions for the management of municipal and industrial solid, semi-solid, and liquid residues. The simple self-learning presentation style is designed to encourage deep understanding of the process principles, plant types and system configurations, performance capabilities, operational and maintenance requirements, post-treatment needs, and management options for coproducts without complex biochemical terminologies and equations. It describes key aerobic biological treatment processes used in conjunction with anaerobic biological treatment in feedstock pre-treatment and in post-treatment of by-products. Practical pre-treatment processes, techniques and operations are described alongside additional treatment techniques of biogas, digestates and treated effluents for various end use options. Effective applications in developing countries are also considered, enabling practitioners and plant operators to effectively apply technology in temperate and warm climatic conditions.
NUMGE 2018 is the ninth in a series of conferences on Numerical Methods in Geotechnical Engineering organized by the ERTC7 under the auspices of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). The first conference was held in 1986 in Stuttgart, Germany and the series continued every four years (1990 Santander, Spain; 1994 Manchester, United Kingdom; 1998 Udine, Italy; 2002 Paris, France; 2006 Graz, Austria; 2010 Trondheim, Norway; 2014 Delft, The Netherlands). The conference provides a forum for exchange of ideas and discussion on topics related to numerical modelling in geotechnical engineering. Both senior and young researchers, as well as scientists and engineers from Europe and overseas, are invited to attend this conference to share and exchange their knowledge and experiences. This work is the first volume of NUMGE 2018.
Constructed Wetlands (CWs) are among the few natural treatment systems that can guarantee an efficient wastewater treatment and an appealing green space at the same time. However, they require large areas for their construction, which is not available in many cases. In this thesis, two domestic wastewater treatment options were designed and studied with the purpose of having a low space requirement: the Duplex-CW and the Constructed Wetoof (CWR). The Duplex-CW is a hybrid CW composed of a vertical flow CW on top of a horizontal flow filter. The stacked arrangement is the key for reducing the CW footprint. The CWR is a shallow HF CW placed on the roof of a building, thus it does not occupy any land. Several modifications and improvements have been tested, in addition to the study of the treatment performance, in order to select the most appropriate Duplex-CW and CWR design. Overall, this thesis contributes to the development of two efficient domestic wastewater treatment technologies. The Duplex-CW area requirement is still higher than many CWs and therefore further improvements are necessary. The CWR is the foremost option to save land areas since it requires 0 m2 of land per person equivalent.

Is it possible for individuals to tackle waste by recycling, reusing and reducing alone? This provocative book critically analyses the widespread assumption that individuals and households have created our global waste crisis. Sociologist and waste expert Myra J. Hird reveals neoliberal capitalism's fallacy of infinite growth as the real culprit, and demonstrates how industry and local governments work in tandem to deflect our attention away from the real causes of our global waste problem. Hird offers crucial insights into the relations between waste and wider societal issues including ongoing (settler) colonialism, poverty, racism and sexism, and showcases how sociology may provide solutions through a 'pubic imagination' of waste.
Edited by Reinhard Kirsch, this book demonstrates the use of geophysics for the detection and delineation of groundwater resources. As well as being an excellent reference, it could also be used as a textbook. An addition to the bookshelf of any geophysicist.
